I am a master's student in Business Economics and I'm new to RapidMiner.

For my thesis, I have to pre-process multiple Pdf files by tokenizing, stemming, transforming cases etc. 
If I do this for one file, I get the wanted outcome: a processed text. But when I use the loop function to process multiple pdfs, the output is never text, but tables of word counts. 

How do I pre-process multiple pdf files and get all the processed texts? 

Thank you for helping!
